Sizing, installation and commissioning
As a general rule, six Greenskies Solar-Lux tubes should be enough for 100 litres of hot water, although collectors should be sized for the hot water demand of each property accordingly.
Suitable sizing software should be used where appropriate. We offer two solar sizing calculators:
Important installation notes
Greenskies Solar-Lux evacuated tubes should be installed with a minimum pipe length of 5 metres flow and 5 metres return pipe work between the collector and the pump station.
It is also recommended to fit a pre-cooling vessel to protect the expansion vessel from the high temperatures involved.
When commissioning a Solar-Lux 6 or 12 tube system, a filling pump must be used to fill and vent the system. A TDS100 or TDS300 controller must be used with an evacuated tube system and evacuated tube mode should be selected within the controller when commissioning.
